- Added impulse response analysis: upload a WAV from REW or ARTA and you get EDC, EDT, T20 and T30, RT60, plus the clarity metrics C50, C80, and D50. Everything runs in the browser, the file never leaves your device.
- A first-reflections calculator maps the points on walls, floor, and ceiling where early reflections land using the image-source method and tells you which to treat first.
- A speech-clarity calculator built for podcasters, lecturers, and home studios. The plain rating — "clear", "slightly boomy", "muffled" — gives a quick read on the room, and the full STI / RASTI model is there when you need to design from numbers.
- Added a room noise-level calculator: rated against NC and SanPiN-2021, with HVAC, outdoor noise, and indoor sources tracked separately. It also shows what happens to the rating if you remove the loudest source or improve windows by 5 dB.
- A subwoofer placement guide walks through five typical layouts with diagrams, explains how to find the listening sweet spot for each one, and predicts the resulting frequency response.
- The "room analyzer" is now the "spectrum analyzer" — the name finally matches what the tool actually does. Capture has two modes: infinite, or run until the spectrogram fills. The page now states upfront that a built-in laptop or phone mic is not a measurement device.
- A QRD and Skyline diffuser calculator: pick the lower target frequency and the maximum cell depth, and you get a ready-made grid of cell depths along the sequence plus an estimate of the working range.
- A Superchunk corner bass-trap calculator works the geometry from side length, depth, and fill density, returning total volume, material requirement, quarter-wave cutoff, and the absorption curve by octave.
- A perforated-resonator calculator. Set the perforation pitch and diameter, panel thickness, and the air gap behind the panel — see the resonance frequency and the absorption curve across frequency.
- The Helmholtz resonator calculator now lets you set the neck cross-section by either diameter or area, supports solving backwards from a target frequency to the geometry, and warns when the chosen configuration cannot physically be built.
- Added a real-time room analyzer: the screen shows a live spectrum, a spectrogram, and RMS/peak meters, driven by the connected microphone
- Online tuner: fixed microphone initialization error and added detailed guidance when the device is unavailable
- Expanded the monitor catalog: added Dynaudio, Eve Audio, HEDD Audio, Amphion, Tannoy, ATC, Barefoot Sound, PMC, Kali Audio, Avantone Pro, and new entries from PreSonus, Yamaha, JBL, KRK, ADAM Audio, Genelec, Focal, Neumann, and others
- Refined visual design: section icons, spacing, and typography unified across the app
- Interface copy cleaned up: sharper terminology, clearer wording
- Improved calculation accuracy in the critical distance, membrane absorber, and SBIR tools
- Planner now opens in freeform mode by default — the step-by-step wizard is available from the sidebar
- Mode switchers across calculators have been clarified
- Hover hints added next to use-case and strategy options in the ROI calculator
- Use-case selector moved to the sidebar — no longer takes up the top strip
- Problem resonance ranges are now shown as a table — easier to compare
- Confidence and data-source labels unified to a consistent style
- Echo train and diminishing returns charts span the full card width — easier to read
- Terminology corrected, interface labels updated
- General UI improvements
- Dark theme refinements
- Planner improvements
- Bug fixes
- Room analysis calculators: room modes, RT60, SBIR, flutter echo, Bonello chart, Bolt area
- Room acoustic profile and microphone-based spectrum analyzer
